plunger, the latter being packed by a To all whom it may concern:

Be it known that I, RUSH J. BETTIhoNE, of Stillwater, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in Direct-Actin g Steam-Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the'art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in direct-acting steampumps.

The object of the invention is to provide a steam-pump. which shall be simple and durable in its construction, of small initial cost, and adapted to be operated at a minimum expenditure of power; and with these ends in view my invention consists, first, in the combination, with a steam-piston, water-plunger, and slotted link, the latter arranged diagonally to the piston and plunger, of the crankpinkand sliding block located in the diagonal lin My invention further consists in certain other details in construction and combinations of parts, as will hereinafter be explained, and pointedout in the claims.

In the accompanying drawings, Figure l is a view in front elevation of my improved pump. Fig. 2 is a side elevation, and Fig.3 is a detached view of the diagonallink. i

A represents the steam-cylinder, and B the steam-chest. Any. suitable construction or form of valve may be employed for regulating the admission of steam to the steam-cylinder for actuating the piston.

O is thepiston-rod, and D the gland of the stuffing-box D for packing the piston-rod.

E is the water-cylinder, and F is the watersuitable stufling-box, c, and gland e.

Piston-rod G and plunger F are connected by the link G, which is arranged diagonally to such parts as are shown in Fig. 3. a

The piston-rod, plunger, and link are all made solid and in a single piece, which construction is of light cost in its manufacture,

. pensed as all fitting and fastening of the parts is diswith, and also there is much less liability of any disarrangement or breakage of the parts when made in the manner described.

Within the slot H in the diagonal link G is located a sliding block, I, in which is received the crank-pin J the latter being secured to or connected with the wheel or disk K attached tothe shaft K, the inner end of the latter being supported in a bearing, k, in the yoke L, and the outer end in a bearing, 70, on the upper end of the bracket M.

An eccentric, N, is attached to the shaft K at a point between the bearings 70 k, and ed circling the eccentric is an eccentric strap or yoke, N, outer end of the valve-stem 0.

To the outer end of the shaft K is secured the fiy-wheel P, which may be provided with a handle, Q, so that the pump may be operated by hand if desired.

Steam being admitted to the steam-cylinder operates to reciprocate the piston and plunger in the usual manner.

The diagonal link serves to impart rotary motion to the shaft K, and thereby. operate the slide-valve through the medium of the eccentric. The slotted diagonal link for imparting motion to the crank-wheel obviates the great objection incident to the employment of the ordinary link, which is arranged at right angles to the stroke of the piston. In the latterit' ell known that-considerable power is expended in carryin g the crank over its dead centers, and, as the result of such construction, the wearon the parts is unduly great,

causing a thumpingjiof the piston as it passes over its dead-center's? By arranging thelink diagonally to the stroke of the piston the sliding block in which the crank-pin is located is caused-.to move between inclined walls, and thus \i lien the crank is on its dead-centers the block,instead of being located between walls of direction in which the power is applied, is located between inclined walls or guides which allow the block to be readily moved irrespect: ive of the position of the crank, and prevents undue wear of the parts, and, further, obviates or guides arranged at right angles to the line the thumpingorjarringof the piston and other I diagonally to the piston-rod and Water-plunparts of the pump while in operation.
